To all wlaoinit may concern;

Beit known that I, Gnonon SEWELL, of Brooklyn, in thecounty of Kings andState of New York, have made a new and useful Improvement in.Hose-Oouplihgs; and-I hereby declare the following to be a full andexact description of the same, reference being bad to the accompanyingdrawing forming part of this spccifieation. 4

My invention consists in certain improvements and modifications of thehose-coupling described in in patent of February; 8th, 1870, No. 99,715.I

The first modification an'd improvement-is shown in I Sheet I ofdrawing, in which A A are the partsto which the hose is attached. B, thecollars for locking the parts together in coupling.

O O O G are segmental cam flanges, each being a quadrant, or the fourthpart of acircumference. In this form of coupling the parts are simplyreversed 99,715. Instead of segmental lugs connected with the parts A A,there are-segmental cam-flanges; and instead of segmental cam thinges onthe collar, there are segmental grooves, so as to' lock with the flangeson the parts A A. Y

The two parts which form this coupling are exact duplicates the one ofthe other. The following is the mode .of joining the couplings: Thecollar 13 is turned a quarter round from the position shown in the lowerfignre'in Sheet I, so that the collar-flange D is brought along side ofthe flange O.

The two parts of the coupling may then be brought together, the flangesG of the one part entering be-" tween the ends of the flanges D of theother part. Then, by turning the collars in opposite directions, theflange D'of the collars will pass under the flange 0. As the flanges arein the form-of inclined planes they wedge together and mesh each partclosely against the other, so as to form a water tightgjoint. i Thepacking-ring E will assist in closing the joint. The coupling formed inthis manner is very simple and durable. Theflanges and grooves are allcovered up and protected by-the collars B B, so that the hose with thiscoupling may be roughly handled without danger of breakage or injury.

Another modification of my invention is shown in Sheet II of thedrawing. In this form the parts are not exact duplicates of each other,but are counter-. parts, that is, male and female. The upper figure inSheet II shows the male or piston,andthe lower figure the female orsocket portion. The male part A carries the locking-collar B,jwhichisconstructed the same as in patent No. 99,715, with segmental cam-flangesor inclined planesQ;

The collarjBis heldto the partA by a stud which segmental flanges b,which are moves in a slot, D, which permits the collar to turn through aquadrant. V

0n the socket portion are also segmental flanges F in the form ofinclined planes,audon the male or piston portion are correspondingplane-flanges E. The collar B has on its lower edge two segmentalflanges O in the form of inclined planes. I The following is the mode ofconnecting this form of coupling The collar is placed as shown in theupper figure in,

Sheet II, so that the flanges 0 and E coincide. The

parts may then be brought together, the flanges 0 and" E going betweenthe flanges F F, until the end of the flange O rests againstthe-'stop-G, which is fastened in the bottom of the socket. Then, byturning the collar, the flanges O- on the collar are brought under theflanges F on the socket, and,' heing in the form of in cliued planes,draw the parts closely together and look them.

The stops G prevent the parts turning on each' other, and so prevent theco the collar is turned.

The third modification and improvement is shown in Sheet III ofthe'drawing, in which- Figure 1 is a perspective view of one part of thecoupling;

Figure 2 is a sectional elevation of the sleeve on binding-ling;

Figure 3, a perspective view ofthe otherpart of the coupling; Figure 4is a plan view of the part shown in fig. 2; and

Fignreo, aplan view ofthe part shown in fig. 1.

In this. forin of my invention theparts are not du-. plicates of eachother, but are substantially the reverse of the form shown in Sheet II..In Sheet II the collar is permanently attached to one-half of thecoupling, so as to form the socket, and the locking device enters it,and turns inside of it, so as to lock the inclined planes together.- Inthe form shown in Sheet III, the collar turns over the flanges similarto the form shown in Sheet I.I

v The following are the parts shown in Sheet III oi. the drawing:'

A and -B are the parts to which the ends of the hose are attached. On Aare segmental flanges a a in the form of wedges or inclined planes, eachbeing a quadrant, (see figl 5.) 0n the part B are corresponding notwedge-shaped. The'collar O has onits inside .two segmental flanges. e,which are in the form of inclined planes, and ontlie opposite edge acontinuous flange, m m, with two steppins (1 d, The collar 0 is passedover the portion B,

so that the flanges b b rest in the bottom of the collar on theflange-m, the ends of the flanges b b restpling from unlocking tillformshown in Sheet II.

ing against the stops d d. I When the collar is placed a on the part Bit will resemble the socket portion of the'c'oupling shown in Sheet II,with this difference, however, that the collar 0 revolves through aquarter of acircle.ou the part B, and does notrevolve in the The.following is the modeofusing this form of my inventioni Y The parts areunited by bringing the part A in such a position that the flanges a a,enter between the v flanges e e. 011 the part B are project-ions h h,which enter small sockets in the face of the flanges a a, so that, whenbrought together, the parts A and B cannot turn on each other. Then, byturning the collar 0,

the flanges ee are brought overtbe flanges a and b, and lock themtogether, each pair of flanges-a 6 being pressed between the flange eand the bottom flange m of the "collar; v

In all the forms of my coupling there are certain common features. Inthat described in my patent of February 8th, 1870, the two parts whichare attached to the hose are divided on the outer edge into foursegments, each alternate one of which being removed,

so that-the parts interla'ce the one'wvit-h .theother. Thesameconstruction as to the four divisions is adhered to in all theforms. The parts,: when brought together, are then locked by means ofacollar with -.flanges in 'tbeform-of inclined planes, which engage Vwith corresponding flanges on the two parts of the coupling, Intwo ofthe forms,'viz, in that described and those on the'c'ollar projectoutwardly.

in pateuti N o. 99,715, and in that shown'on Sheet 1 of the drawingwhich forms part of this specification, there are duplicateclocking-collars with flanges, but either collar alone willanswer. Inthe first the flanges on the pieces connected with the hose projectinwardlty, In 1- no form shown on Sheet I, the relative position isreversed, that is, the flanges on the pieces connected with the hoseproject outwardly, and those on the collars project inwardly. Acorresponding change of the relative position of the flanges makes theprincipal difference between the forms shown in Sheets II and III.

In all the formsI have shown only four segments,

but the same mode of coupling could be carried out by making six, eight,orother even number of equal divisions, each alternate one beingremoved.

- Having thus described my invent-ion, -What I claim, and desireto'secure by Letters Patent of the United States, is-.

1. A hose-coupling, formed by means of a tubular fportio'n withsegmental flanges, in combination with a locking-ring, withcorresponding flanges in the form of inclined plaues,substantia-lly asdescribed.'

2. The parts-A A, with segmental flanges G G, in

combination with the collars B B, having corresponding flanges D D,substantially as described.
